Abstract
In a non-contact power transmission system, the radial distance of a power reception coil relative to a power transmission coil is detected on the basis of the weak voltage value corresponding to the amount of weak power received by the power reception coil, and moreover the moving amount is detected on the basis of the change in level of the detected weak voltage value and furthermore, the moving direction is detected. Thus, the position (distance) of the power reception coil relative to the power transmission coil is detected.
